While that will work in the given scenario, I'd personally prefer just
pkg_libchk -q -o.

There may be a few notorious false positives (mostly packages bypassing
the regular ld.so stuff - Mozilla stuff -, or ports dynamically loading
facultative UI libraries, such as Opera that can use GTK and Qt, or
ports that need compat* stuff for bootstrapping, such as diablo-jdk on
newer computers).
